ext/phar/phar_object.c in PHP before 5.5.32, 5.6.x before 5.6.18, and 7.x before 7.0.3 mishandles zero-length uncompressed data, which allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted (1) TAR, (2) ZIP, or (3) PHAR archive.

This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.

Overflow Buffers

Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.

Client-side Injection-induced Buffer Overflow

This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.

Filter Failure through Buffer Overflow

In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).

MIME Conversion

An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

Overflow Binary Resource File

An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.

Buffer Overflow via Symbolic Links

This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.

Overflow Variables and Tags

This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.

Buffer Overflow via Parameter Expansion

In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.

Buffer Overflow in an API Call

This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.

Buffer Overflow in Local Command-Line Utilities

This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4395)
- A remote code execution vulnerability exists due to an overflow condition in the mod_smh_config.so library caused by improper validation of user-supplied input when parsing the TKN parameter supplied to the /Proxy/SSO endpoint. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-4396)
- An out-of-bounds read error exists in PHP in the php_str2num() function in bcmath.c when handling negative scales. An unauthenticated, remote attacker can exploit this, via a crafted call, to cause a denial of service condition or the disclosure of memory contents.
(CVE-2016-4537)
- A flaw exists in PHP the bcpowmod() function in bcmath.c due to modifying certain data structures without considering whether they are copies of the _zero_,
_one_, or _two_ global variables. An unauthenticated, remote attacker can exploit this, via a crafted call, to cause a denial of service condition. (CVE-2016-4538)
- A flaw exists in PHP in the xml_parse_into_struct() function in xml.c when handling specially crafted XML contents. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
(CVE-2016-4539)
- Multiple out-of-bounds read errors exist in PHP within file ext/intl/grapheme/grapheme_string.c when handling negative offsets in the zif_grapheme_stripos() and zif_grapheme_strpos() functions. An unauthenticated, remote attacker can exploit these issues to cause a denial of service condition or disclose memory contents.
(CVE-2016-4540, CVE-2016-4541)
- A flaw exists in PHP in the exif_process_IFD_TAG() function in exif.c due to improper construction of spprintf arguments. An unauthenticated, remote attacker can exploit this, via crafted header data, to cause an out-of-bounds read error, resulting in a denial of service condition or the disclosure of memory contents.
(CVE-2016-4542)
- A flaw exists in PHP in the exif_process_IFD_in_JPEG() function in exif.c due to improper validation of IFD sizes. An unauthenticated, remote attacker can exploit this, via crafted header data, to cause an out-of-bounds read error, resulting in a denial of service condition or the disclosure of memory contents. (CVE-2016-4543)
- A man-in-the-middle vulnerability exists, known as 'httpoxy', in the Apache Tomcat, Apache HTTP Server, and PHP components due to a failure to properly resolve namespace conflicts in accordance with RFC 3875 section 4.1.18. The HTTP_PROXY environment variable is set based on untrusted user data in the 'Proxy' header of HTTP requests. The HTTP_PROXY environment variable is used by some web client libraries to specify a remote proxy server. A remote attacker can exploit this, via a crafted 'Proxy' header in an HTTP request, to redirect an application's internal HTTP traffic to an arbitrary proxy server where it may be observed or manipulated.
